Azalea's "Seven Sevens and Fears"
One, acid afraid of alkali. Azaleas prefer acidic soils that grow poorly or even die in alkaline or alkaline soils. The soil acidity is suitable for ph5.3. The proportion of azalea nutrient soil is 4-6 parts of rot leaf (preferably coniferous), 0.1-1 part of moss and 3 parts of river sand. Secondly, watering also needs to be done with acidic water, and the family can use decocted (fermented) rice water or tap water and vinegar (slight discoloration). Second, I am afraid of fear. Rhododendron sex hi moist soil. The principle of watering is: Seeing wet, seeing soil, not pouring, once drenching, avoiding accumulation. Third, cool and afraid of heat. The suitable growth temperature for azaleas is 15-25°C. When the temperature is higher than 25°C, cool down promptly. Move the plants to the shade, spraying water on the foliage and the ground to enhance ventilation. In the summer in the north, the plants are placed in the morning and evening light, and in the winter, they enter the room. Fourth, hi shame afraid of light. Rhododendron grows well in half shade, but it is easy to burn when it encounters strong light. The first light is easy to make the leaves dry, and then the entire leaf dry, fall off, branches are also prone to wilting, dry. This is mainly due to the strong light and high temperature, the rhododendron leaves a large amount of water evaporation, the lower part of the water supply, and thus wilt, dry. Five, hi small winds afraid of strong winds. Azalea hi-branch. Poor ventilation is prone to pests and diseases, but it is also afraid of strong winds, especially dry gale and dry hot winds, which have a great impact on it. Sixth, hi moist white dry. The air drying in the north is very unfavorable to the growth of azaleas. Drying is one of the important causes of death of the Northern Rhododendron, so it is very important to create a moist environment. In addition to spraying the water once or twice a day and spraying the water 1-2 times on the ground, it can be covered with plastic bags at night and opened during the day. Keep humidity at 70-90%. Seven, fertile and afraid of big fat. Rhododendron flowers hi fertile soil, fertilization should be cooked with soybean cake fat, sesame sauce slag, rotten eggs, etc., choose one of them as the main fat, add 50% soil after mixing, stir evenly, as a solid fertilizer after fermentation. Can also be used as liquid fertilizer. Mainly organic fertilizer, fertilizer for the nursery. All-element flowering fertilizer can be used during the growing season. The principle of using thin fat fertilizer for fertilization is a big fertilizer (concentrated fertilizer) that can easily cause fertilizer damage.
